Abstract :
This paper presents time synchronization in the OFDM receiver using a preamble based on generalized chirp-like (GCL) sequence. The synchronization method is based on correlation of the preamble using Schmidl-Cox technique and also Park´s technique. It is shown that GCL based Park´s technique is a superior and robust time-synchronization technique as compared to the pseudo-noise (PN) sequence based technique, particularly in the presence of frequency offsets.
